Revealed: What causes pancreatic cancer

As one of the common malignant tumors of the digestive tract, pancreatic cancer is the most common malignant tumor and mostly occurs in the head of the pancreas. So what are the causes of pancreatic cancer ? Let's talk about the causes of pancreatic cancer.

Pancreatic cancer is usually caused by:

1. Smoking. Animal tests have proven that feeding animals with tobacco acid water can cause pancreatic cancer. A large sample survey showed that smokers are 1.5 times more likely to develop pancreatic cancer than non-smokers. The more you smoke, the higher the chance of developing pancreatic cancer. For example, the incidence of pancreatic cancer in men and women who smoke one pack a day is 4 and 2 times higher than that in non-smokers, respectively. The above data show that smoking can induce pancreatic cancer in some people.

2. Improper diet. In recent years, some scholars have attributed the increase in pancreatic cancer to improper diet. Animal experiments have shown that animals fed with a high-protein, high-fat diet can accelerate the renewal of pancreatic duct cells and increase their sensitivity to carcinogens. Domestic scholars Shen Kui and others have clearly stated that dietary structure is closely related to the occurrence of pancreatic cancer, and people who eat a lot of meat are more likely to develop this disease. Japanese scholars pointed out that the increase in the incidence of pancreatic cancer in Japan in recent years is related to the Europeanization of the Japanese diet. That is, eating too much high-protein and high-fat. Some scholars also believe that people who drink coffee have a greater chance of developing pancreatic cancer, but this has not been further confirmed.

3. Abnormal gene expression and pancreatic cancer. There are many genetic studies on pancreatic cancer. Abnormal gene expression is closely related to the cause of pancreatic cancer. The relationship between the occurrence of various tumors and cell genes is currently a hot spot in the study of the cause of cancer. Among various gene families, the mutation of the 12th site of the K-ras gene is closely related to the occurrence of pancreatic cancer, and the inactivation of the tumor suppressor gene P53 and the recently cloned MTS1 also has an impact. Since the occurrence of cancer is a multifactorial process, there may be activation and inactivation of multiple oncogenes or tumor suppressor genes, and it is also related to family inheritance.

The above is an introduction to the causes of pancreatic cancer. I hope it will be helpful to everyone. Understanding and recognizing the causes of pancreatic cancer can help pancreatic cancer patients receive better treatment and control the deterioration of the disease.
